Pro-democracy campaigners took to the streets of Hong Kong on Sunday, but in far smaller numbers than expected, before a vote on a political reform package that has divided the city and sparked mass protests.

With days to go before lawmakers vote on a controversial political reform package that has split Hong Kong, pro-democracy protesters who have camped out at the legislature for months are preparing to go home.

Two Hong Kong journalists who just returned from a news coverage mission in South Korea have been quarantined for fear of contracting the Middle East respiratory syndrome (MERS), according to a report on the Apple Daily's website Sunday.

Tens of thousands of Hong Kongers joined a candlelight vigil Thursday night marking the crushing of the 1989 student-led Tiananmen Square protests, an annual commemoration that takes on greater meaning for the city's young after last autumn's pro-democracy demonstrations sharpened their sense of unease with Beijing.

Hong Kong pro-democracy lawmakers said on Sunday they would "definitely" veto the government's planned political reforms after a last-ditch meeting with Chinese officials failed to reach any agreement.

Malaysia barred a veteran Hong Kong pro-democracy lawmaker from entering the country Friday branding him a "troublemaker," days after student leader Joshua Wong was denied entry over fears he would threaten ties with China.

Hong Kong student leader Joshua Wong was on Tuesday refused admission to Malaysia, where he planned to speak about the city's pro-democracy movement and the anniversary of China's Tiananmen Square massacre.
